Missing Diffs

[ali-ghanbari]

Hi,

Thanks for this useful library.
When parsing the attached unified diff file, I noticed that the library fails to retrieve all the diffs (it only sees the first one).
I am not sure if the format of the file is correct; when I delete the blank lines between the diffs the library works just fine.
I am guessing this might be a bug in the library, and it would be ideal to fix it.

Here is my use case:

final DiffParser parser = new UnifiedDiffParser();
try (InputStream is = new FileInputStream("test.patch")) {
   System.out.println(parser.parse(is).size()); // This is supposed to print 2, but it prints 1: it only sees the first diff!
}

And here is the patch file test.patch:
